A small region in Iraq just became one of the oil market’s biggest concerns

Following the referendum, Turkish President Recep Tayyip Erdogan threatened to shut down a pipeline that transports about 500,000 barrels of oil per day from Iraqi Kurdistan to Ceyhan, Turkey. That daily volume is just shy of the total supply reductions that a group of oil exporters led by Russia made this year in order to help OPEC drain a global crude glut.

“The saber-rattling from Erdogan really spooked the market,” said John Kilduff, founding partner at energy hedge fund Again Capital. “This is the first time we’ve seen oil threatened as a diplomatic weapon for a while.”

Brent crude prices surged 3 percent on Monday as Kurds went to the polls, hitting a 26-month high of $59.49 early on Tuesday. U.S. crude topped out at a five-month peak of $52.43. Prices fell on Tuesday as traders took profits and concern around the referendum eased, Kilduff said.

The region is likely to see a cycle of escalation before tensions ease, said Ayham Kamel, head of Middle East and North Africa practice at Eurasia Group, a risk consultancy.

The Iraqi government has asked oil traders to stop dealing with the Kurds directly and ruled out talks on a Kurdish exit. Iran closed its border and halted flights to the Kurdish region, and Turkey is threatening sanctions.

Still, all parties are wary of stoking economic crisis and ethnic violence, Kamel said.

“The most likely outcome is not going to be a permanent shutdown of the Kirkuk-Ceyhan pipeline because that would completely shut down the Kurdish economy and undermine the stability of the region, which is not a primary target of either Baghdad, Ankara or even Tehran,” he said.

Iraqi Kurdistan has built positive, bilateral relations with its neighbors, so severe economic sanctions would hurt all sides, said Bilal Wahab, a fellow at the Washington Institute for Near East Policy.

Kurdish oil generates the revenue that Kurds use to buy food from Iran and Turkey, pay Turkish construction firms to develop its cities and fund trips to Istanbul by Kurdish tourists, Wahab notes. The Anglo-Turkish oil company Genel Energy is one of the biggest players in Iraqi Kurdistan.

“What [the Kurds] are bracing for is either more bluster or some short-term punitive measures,” Wahab said.
